# Array (list of objects)

## Overview

In order to use an array of objects field, add `children` and `type: InputType.Array` to your `FieldConfig`.

It is only used for objects, if you want other arrays like `text` please use `InputType.MultiText`

```jsx
children: { fields: FieldConfig[] },
type: InputType.Array,
```

## Interface

```typescript
interface FieldConfig {
  key: string;
  type: InputType.Array;
  children: { fields: FieldConfig[] };
  label?: string;
  isDisabled?: boolean;
  isRequired?: boolean;
  defaultValue?: any;
}
```

* `key`: A unique identifier for the field.
* `type`: The type of input to use for the field, as specified by the `InputType` enumeration.
* [`children`](/api-reference/field-config.md#children): A nested set of fields.
* `label`: (optional) The label to display for the field.
* `isDisabled`: (optional) A boolean value indicating whether the field should be disabled.
* `isRequired`: (optional) A boolean value indicating whether the field is required.
* `defaultValue`: (optional) The default value for the field.

An array of a nested set of fields for use with `InputType.Array` fields. This allows you to add, edit and delete multiple objects in an array.

**Properties**

* [`children`](/api-reference/fields/nested-children.md): The nested children configuration, [view docs](/api-reference/field-config.md#children)

## Example

Here is an example of how the `children` property can be used in a `FieldConfig` object:

```javascript
const passengersFormConfig: FormConfig = {
  fields: [
    {
      key: "passengers",
      label: "Passengers",
      type: "array",
      children: {
        fields: [
          {
            key: "email",
            label: "Email",
            type: "text",
            isRequired: true,
          },
          {
            key: "first_name",
            label: "First Name",
            type: "text",
            isRequired: true,
          },
          {
            key: "last_name",
            label: "Last Name",
            type: "text",
            isRequired: true,
          },
        ],
      },
    },
  ],
};
```

In this example, the passengersFormConfig object represents a group of fields that are used to add, edit and delete multiple passengers to the form.

## Example Output

```json
{
  "passengers": [
    {
      "email": "john@tutim.io",
      "first_name": "John",
      "last_name": "Doe"
    },
    {
      "email": "may@tutim.io",
      "first_name": "May",
      "last_name": "Smith"
    }
  ]
}
```
